Neurogenic Fever in Severe Traumatic Brain Injury Treated with Propranolol: A Case Report

The causes of intractable fever in severe traumatic brain injury (TBI) patients can be diverse. Neurogenic fever (NF) which is a rare entity can develop due to autonomic dysregulation in the absence of infection or any other cause of fever. It manifests as fever, tachycardia, paroxysmal hypertension, dilated pupils, tachypnea, and extensor posturing in cases of severe TBI, brain neoplasms or brain haemorrhage. We found propranolol to be effective in controlling many of the manifestations of neurogenic fever in our patients with severe TBI. Fever in severe TBI patients is not an uncommon phenomenon, but when intractable with negative fever workup, a central cause should be considered. Propranolol is deemed as one of the most efficacious drugs for managing NF due to dysautonomia. We want to apprise the readers about this entity and its treatment with beta-blockers.
